PRUNING-SAW.

Application filed February 23, 1910.

Specification of Letters Patent.

To all whom "it may concern:

Be it known that I, JOSEPH S. BENNETT, a citizen of the United States,residing at Fayetteville, in the county of Washington and State ofArkansas, have invented certain new and useful Improvements inPruning-Saws; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to pruning saws of the class in which the saw teethare set to face the handle whereby the sawing operation is on the inwardstroke instead of on the outward stroke, as is usual with wood saws.

My object is to provide a Very strong and rigid connection between theframe of the saw and the handle block so that there will be no danger oftheir coming apart While the saw is being used.

Another object is to provide for empl0ying an extra long blade byshaping the frame in such a manner as to hold said blade taut andprevent it from buckling, which a long blade is apt to do and which itis hard to prevent in the commonly used rectangular saw frame.

The invention consists in the features of construction and combinationsof parts hereinafter described and specified in the claims.

In the accompanying drawing illustrating the preferred embodiment of myinvention: Figure l is a side elevation of the saw constructed inaccordance with my invention. Fig. 2 is a top edge view. Fig. 3 is abroken section on the line m0a of Fig. 2, and Fig. 4 is a detailedsection on the line y-ay of Fig. 1.

Referring more particularly to the drawing, 1 designates the handleblock which is provided with the usual handle 2 and a passage o-r hole 3extending through it edge- Wise from top to bottom and positioned wellinward of the end of the block opposite the handle. This inner end ofthe block has its upper corner protruding, as at 4, beyond its lowercorner. The upper face or edge of this protruding corner is grooved, asat 5, Fig. 4, to receive the frame 6. The frame is preferably made ofone quarter inch pipe so as to be light and strong. It is bent into thegeneral form of the short side and hypotenuse of a right angle triangle,the

blade 7 which is secured between the ends of said frame forming theother side of the triangle. The bend in the frame is preferably rounded,as at 8. The passage or hole 3 and groove 5 in the handle block areshaped to fit the short side and curved portion at the bend in theframe. It 'will be noted that the protruding upper corner 4: of saidhandle block serves as a brace to support the long extending portion 9corresponding to the hypotenuse of the triangle. I propose to make thesaw frame twentyfour inches long and it is necessary to pro- Vide somemeans for bracing it when made such a length in order to prevent it fromsagging at its outer end which would cause the blade to become slack andvery apt to break. The extension of the upper corner of the block belowthe inner portion of said extending part of the frame in the form of.

a brace, as shown, is a simple and cheap way of accomplishing thispurpose.

If desired, a screw or bolt 10 may be inserted through the frame intothe protruding portion 4 of the handle block, as illustrated in order tohold the portion of the frame, through which it is passed, firmly downin the groove 5. This may not be necessary because the frame will beheld in the slot in the handle-block by the connection between the bladeand the lower end of said frame which projects below said handle-block,said connection being arranged immediately below said block so that theblade contacts therewith. The portion of the handle-block arrangedinteriorly of the frame is preferably reinforced by screws or bolts 11passed through it from side to side so as to prevent said block fromsplitting under strain. It will also be noted that the handle extendsbelow the blade so that the force used in operating the saw, whengripped in the hand, is exerted in linewith said blade where it is mosteffectual.

While my invention, as described herein, is especially designed forpruning saws, its novel features of construction may also be employed onsaws used for other purposes. It should also be understood that I do notlimit myself to the details of construction herein shown and described,but reserve the right to make such changes as fairly fall within thescope of the appended claims.

By extending the handle below the blade so that the pull is in line withthe cutting edge, the saw is not capable of cutting faster but the useof a very narrow blade is permitted because it will not pinch or bind inthe kerf. I can,'therefore, provide a saw with a very long blade whichis at the same time very narrow without danger of it being broken inuse. These advantages taken with the draw-cut previously described, makemy saw especially useful for the purposes for which it is designed.

I claim 1. In a saw, the combinatiomwith a frame comprising a strip bentto form a long arm and a short arm, of a handleblock provided with ahole extending edgewise therethrough and positioned well inward from theedge thereof, the short arm of the frame extending through said hole inthe handle-block, the portion of the long arm, adjacent to. the shortarm engaging the upper edge of said handle-block, and a blade secured atone end to the outer extremity of said long arm of the frame and at theother end to the extremity of the short arm, projecting through theopening in the handle-block, immediately below the lower edge of thelatter whereby said frame is secured to said handle block.

2. In a saw, the combination, with a frame comprising a bent strip, anda blade carried by said frame, of a handle-block provided with a holeextending edgewise-therethrough, and a groove in its upper edge, aportion of said strip extending through said hole and another portionseated in said groove whereby the frame is prevented from turning insaid hole.

3. In a saw, the combination, with a frame comprising a bent strip, anda blade carried a es by said frame, of a handle-block provided with ahole extending edgewise therethrough, a groove in 1ts upper edge, aportlon of saidstrip extending through said hole and another portionseated in said groove, whereby the frame is prevented from turning insaid holeand a fastening passed through said strip and into the groovedportion of the handle-block.

4; In a saw, the combination, with a frame comprising a bent strip, anda blade carried by said frame, of a handle-block provided with a holeextending edgewise therethrough and positioned, well inward from theedge thereof, a portion of the strip comprising the frame extendingthrough said hole, the

upper corner of the block inward of said hole being extended below theupper portion of the frame to serve as a brace for the framesubstantially as and for the purpose specified.

5. In a saw,,the combinatiomwith a frame comprising a bent strip, and ablade carried by said frame, of a handleblock provided with a holeextending edgewise therethrougli, and a groove in its upper edge, aportion of said strip extending through said hole and another portionseated in said groove, the upper corner of the block inward of said holebeing extended below the upper portion of the frame to serve as a bracefor the frame, substantially as and for the purpose specified.

In testimony whereof, I my signa-' ture, in presence of two witnesses.
